A
Conversation
between
Marcin
and
ever
so
humble
David,
Lee
from
China
talking
about
coop
model,
open
sourcing
things
working
with
Shenzhen
and
let's
start
on
the
coop.
So
David
tell
me
how
you
think,
since
you
suggested
that
we
should
consider
the
coop
model,
how
would
you
see
that
working
right
now
for
OSE
like
what
would
be
a
tangible
thing?
We
could
do
well.
B
B
The
opening
pages,
the
and
in
this
way
the
revenue
from
the
bond
output
as
it
goes
into
the
the
people,
use
the
short
and
then
people
who
were
commercial
and
open
source
and
open
sources
in
a
book
in
there
for
ways
to
make
the
was
open
source
in
over
wait
for
a
many
no
for
crew
to
work
on
the
same
projects,
because
at
the
end
of
the
day,
a
lot
of
this
service
has
to
come
from
local
starting
would
be
the
open
source
model.
These
two
very
good,
but
they're,
always
mother.
B
Yeah
I
think
anymore.
3D
printer
is
a
little
bit
well
as
a
is
it
a
bit
harder
today
is
the
I.
Think
quite
interesting
is
the
finding
a
cooperative
use
of
the
deep
winter
is
not
as
oh.
We
are
still
looking
for
answers.
A
relevance
to
the
place
where
the
deep
winter
actually
become
is
actually
a
productive
tool.
B
No,
it's
not
it's
not
efficient
to
do
a
reputation
of
a
union
of
hundreds
of
something
with
the
deep
leader
it
has
these
very
specific
up.
Every
single
one
of
them
can
be
customized
that
she
doesn't
really
that
customization
we
can
customize
it,
but
now
we
we
still
haven't
the
other
way
of
the
paucity
of
advantage
for
by
that
customizations.
B
A
A
C
B
And
expansion
and
an
extensive
how
expensive
it
is
I
mean
I.
Was
this
meeting
at
Hipparchus
spoken
of
all
new
office
in
South
America
and
everybody
was
there
showing
the
pictures
of
the
British
and
then
one,
and
that
one
part
of
meeting
go
into
the
discussion
of
me
the
supply?
She
has
a
twin
stop
there
and
the
screen.
We
have
seen
this
pictures
of
a
course
in
stone,
but
the
big
coca-cola
hi
Alec
other.
If
they
can't
issue
the
water
there.
B
There's
an
exchange
mr.
garibaldi,
the
sighting
of
the
global
supply
chain,
diving
at
this
stage.
We
we
have
enough
rich
of
this
conference
to
bring
things
into
sheer
amount
of
come
here
and
the
death
good
development
of
the
different
is
really
silica.
What's
missing,
for
what
we
have
very
venture
to
replace
what
already
already
working
to
something
very
high.
Oh.
A
Yeah,
let's
see
so
what?
What,
for
example,
would
you
say
about
just
exploring
the
concept
of
here?
Let's
give
you
an
example
of
a
part
that
I
3d
printed
for
the
film
and
shredder.
Let
me
just
show
you
this
one
I
want
to
show
you
an
example
where
I'm
asking
where
you
think
that
fits
and
the
scheme
of
3d
printing
cuz,
there's
custom
parts
that
we
can
produce.
But
let
me
let
me
show
you
an
example
of
a
3d
printed
bearing.
C
B
C
A
A
So
so,
there's
a
gentleman,
it's
a
plastic
shredder
and
we
actually
made
a
motor
mount
and
a
bearing
mount
which
are
3d
printed
and
which
would
otherwise
be
impossible
to
make
source
locally.
What
do
you
think
of
that
in
your
scheme
of
that's
augmenting
standard
production
or
that's
replacing,
because
here
it
seems
like
it's
replacing
standard
bearing
holders
because
for
one
like
and
we
couldn't
find
a
bearing
holder
for
that
kind
of
hex
bearing
we
had
there.
B
Well,
I
mean
I
think
this
is
the
it's.
The
yeah
I
mean
I
think
as
a
part,
a
replacement,
but
at
all
it's
a
component
is
a
complementary.
The
core
of
this
is,
you
are
beauty
with
things
easy
to
find
and
back
for
efficient
design,
different
reason.
They
are
customized
parts,
and
it's
going
to
be
that
where's,
the
D
printer
can
do
a
very
good
job,
but
the
whole
thing
is-
and
this
is
Cohen
for
Murray
to
different
in
century
talks
to
but
2d
printer
as
a
tool
and
I.
B
C
B
A
D
C
B
Doe
and
coming
bomb
the
thinking
of
the
what's
the
space,
but
it's
my
open
source
project
can
do
to
starting
to
what
be
helpful
for
the
people
involved
and
in
the
short
term,
can
create
an
IV
paddy,
and
one
of
the
second
stubborn
is
the
the
low-speed
vehicle.
The
low-speed,
like
oh
yeah,
the
this
mission
they're
easy
to
do.
They
actually
cheaper
bill.
They
have
immediate
community
application
in
places
like
Africa.
B
That's
a
rapid
need
for
the
G
there's
a
revenue
for
transportation
and
the
and
the
third
thing
is
the
solving
the
problem
with
the
risk
or
the
funding
problem.
So
vehicle
is
a
valuable
access.
Which
means
is
something
can
be
used
as
a
collateral,
always
defect
so
yeah.
So
the
chess
position
when
the
transportation
building
can
be
driven
by
the
men
and
the
demons
I?
Can
she
take
down
alone
to
finance
the
the
building
and
the
car
itself?
The
transportation
itself
is
Toro
productions,
whether
that's
been
used
as
the
transportation
of
goods,
transportation
of
people.
B
B
They
don't
have
to
sign
up
to
the
lid
if
I
sign
up
to
any
office
here
in
the
five
hole,
but
basically
take
the
whole
financing
and,
as
you
just
have
people
creating
the
app
to
extend
in
the
service
yeah
so,
and
this
also
helps
to
call
the
to
grow
EB,
because
right
now,
I
think
one
of
the
issues
Evie
is
the
current
industry
day,
even
though
it's
cheaper
to
do
an
electric
version
of
the
car,
but
they
can
I
drop
the
fight,
the
retail
price
of
their
car.
So
that's
the
that's.
B
B
Mean
if
I,
if
I,
can
sell
you
a
thirty
thousand
dollar
internal
combustion
engine,
I'm
now
going
to
show
you
a
20,000
dollar
version
of
the
same
car
in
electric,
so
the
the
I
mean
they
didn't
assisted
the
insatiable
team,
of
course,
in
a
modern
corporations,
they
cannot
have
drop
in
revenue.
They
cannot
have
job
opportunity.
B
A
A
B
They
can
get,
they
can
get
even
bigger
margins,
I
mean
even
today,
they
introduced
their
car
switch
to
Evie
and
just
show
it
at
the
same
price.
But
it's
not
something.
That's
going
to
be
equitable,
bye,
well,
the
shareholders,
what
investors
of
Wall
Street
as
the!
If
you
have
evening,
if
you
have
a
$30,000
car
today,
Yuri
Reber
action
needs
to
be
it
is
$40,000.
B
$50,000
I
mean
we
got
into
this
really
best
cycle
of
the
the
car
company
will
just
go
out
and
ask
for
government
subsidies
and
taken
I
mean
that's
pretty
much.
Corporate
welfare
I
think
we
right
now
to
localize
eevee
eevee
production
is
making
a
car
manufacturer
car
manufacturing
going
back
to
the
old
days
where
you
know,
cities,
malta,
connection
on
their
production
general
urgent.
One.
B
D
A
B
Yeah
in
the
u.s.
right
now
in
the
regulation,
they
are
not
street
legal;
they
can
only
be
operated
in
the
the
pilot
poverty,
but
that's
a
start
and
I
think
they
are
already
a
lot
of
talks
in
changing
the
Navy
regulation
to
be
more
locally
used
and
I.
Think
one
of
the
the
push
for
this
would
be
people
testing
the
submarine
car.
B
He
loves
me
even
yourself,
really
good
to
be
a
submarine
control
just
because
it's
motor
control
power
steering
and
it's
flexible
platform,
so
I
think
the
booster
with
the
change
in
self
driving.
The
same
way
the
city
can
for
me
self-driving
to
be
operate
within
the
city
limits.
The
same
thing
can
be
can
happen
to
the
NAB
as
well.
It's
yes,
the
laying
out
the
new,
more
localized,
productive
economic
for
the
cities.
B
Couple
more
battery
right
now,
the
the
motor
technology
has
been
advanced
really
fast.
A
lot
of
them
have
been
the
powers
to
be
put
enough
juice
on
it.
They
can
pull
young
said,
certainly
comma
curve,
which
is
around
fifty
miles.
They
could
do
that,
but
the
minute
under
fifty
miles
is
more
of
a
compliance
to
the
regulations.
B
A
B
B
D
C
B
B
A
C
B
C
A
A
B
A
C
D
C
D
D
A
B
A
A
A
B
Butene
factory
from
beginning
in
the
very
top
is
the
establish
the
the
division
co-op
and
a
brain
and
the
initial
small
for
that
small
unit
volume
can
produce
here
and
a
small
in
crop
those
starting
to
take
each
layer
of
the
productions
moving
it
boat,
horn,
local,
the
this
is
the
this.
Is
the
flexibility
of
this
layer
and
stack
spy
chain
every
layer.
Things
should
be
more
to
where
its
most
efficient.
C
A
C
A
A
B
I
mean
for
their
so
for
the
turn.
This
is
poverty,
I
mean
so
each
layer,
different
I,
think
for
car.
When
we
get
you
a
couple
hundred,
that's
very
easy,
a
biblical
assembly,
a
lot
of
component
and
be
sourced
locally
to
get
into
the
economic
scale.
For
the
motors
and
battery
that
probably
starting
having
to
look
at
million
units.
But
it's
all
doable
I
mean
the
the
the
supply
chain
and
the
production
is
very
flexible,
and
it's
also,
hopefully,
by
the
time
the
scale
starting
to
emerge.
B
B
B
Philosophy
of
building,
especially
looking
at
building
your
makerspace,
the
if
we
building
a
production
worker,
kind
of
fear
of
dreams,
kind
of
stuff
kind
of
way
of
thinking,
but
then
but
forgot
to
put
into
thinking
of
the
the
Machine
the
the
people
whose
upper
it's
not
just
machine.
It's
also
people
who's
waiting
to
operate
the
machine
professionally.
B
The
whole
thing
the
ran
everything
adding
up
if
it's
not
producing
and
the
whole
thing
is
just
cheap
on
hiring
up
and
spending
money,
and
that
was
something
incident.
So
many
example
of
the
government
funding
makerspace,
it's
not
it's,
neither
productive
or
it's
now
really
conducting
any
meaningful
education.
B
B
It's
not
just
a
membership
to
share
common
interests;
it's
also
a
membership
to
share
the
living
word.
So
the
thinking
about
how
makerspace
as
a
core
would,
as
she
held
the
help
structure,
to
make
a
space
to
be
more
productive
and
send
as
the
how
the
open
source
how,
where
would
emerge,
we
engage
we
still
this
kind
of
productivity,
space,
yeah.
A
B
A
D
B
A
C
A
D
B
C
A
A
B
Yeah
well,
I
think
there
are
couple
new
may
dissipate
the
the
space
of
an
onion
for
our
prototype
in
the
Bay
Area
I.
Think
the
the
3d
printer
is
a
very
good
interface
to
thinking
of
our
products.
I
mean
it's
a
mess,
you
know,
robot
positioning
and
long
hair
I
think
it's
also
not
just
building
the
3d
printer,
but
also
thing
another.
Another
part
in
look
at
is
the
thinking
about
eco
as
a
ways
to
help
people
get
into
robotics
nothing.
One
of
the
exercise
of
using
3d
printer
is
now
about
2d.
B
Printing,
it's
about
pop,
be
for
me
would
be
that
the
dimensional
woman
of
robotic
arm,
and
that
would
help
to
nothing
with
that
and
abuse
of
the
3d
printer.
That
leads
to
more
interesting
applications.
I
mean
the
thing:
it'll
have
to
be
a
3d
printed
head.
Yes,
it
could
be
anything,
and
this
is
getting
fighting
the
opportunity
to
have
more
people
thinking
about
how
they
can
turn
this
into
a
productive
machine
not
to
not
necessary
to
3d
print,
and
one
of
the
example
would
be,
and
a
lot
of
this
repetitive
testing
words.
B
So
they're
people
building
bio,
lab
viola,
testing,
testing
machine
has
been
using
to
keep
inter
frame
work.
So
I
think
that
that
don't
is
the
and
then
how
to
get
this
machine
selling
them
back
to
as
part
of
a
collection
of
this
3d
printing
buildings.
Yeah
I
think
I.
Think
you'll
be
more
interesting
to
look
at
this,
not
as
just
building
a
3d
printer
as.
A
A
Kits
we
can
offer
a
build
experience
like
like
our
typical
model
has
been.
We
have
people
build
machines
and
we
charge
a
person
three
hundred
dollars
over
the
bill
of
materials
price
to
for
that
experience.
So
it's
basically
I
say
twelve
people
build
their
3d
printers
they'll,
be
like
thirty
six
hundred
dollars.
A
For
that
event,
that
happens
on
a
day
timeframe,
that's
been
our
model,
but
then
then,
there's
other
ways
where
people
you
have
continuing
education
like
to
today,
workshops
where
you
teach
teachers
how
to
one
build
the
printer
into
how
to
use
it
and
how
to
design
things
a
little
bit
so,
for
example,
I
made
3d,
which
is
another
company.
They
charge
two
thousand
dollars
for
a
pair
of
teachers
to
give
them
this.
A
This
two-day
experience,
including
taking
this
or
any
printer
home
to
to
whatever
their
school
or
whatever,
but
no,
no
any
any
further
thoughts
on
that
or
what
you
would
suggest.
We
do
because
we've
got
the
universal
access
system.
I
mean
the
advantage
for
us
is
that
we've
got
like
the
lost,
unique
part
out
in
the
world.
We've
got
the
unique
act,
basically,
the
universal
access
which
we
do
for
X
Y
Z
motion.
You
can
reconfigure
it
in
various
ways.
You
can
scale
it
up
and
so
forth,
have.
C
A
A
That
show
some
of
the
different
variations,
but
that's
that's
what
we
have
and
I'm
wondering
if
you
have
any
suggestions
based
on
that
from
that
enterprise
perspective
and
how
to
make
this
work
economically.
So
if
we
can
produce
a
deliver
product
of
a
3d
printer
with
a
very
flexible
motion
system
which
can
be
expanded
to
other
machines,
like
we've,
also
built
a
CNC
circuit,
a
lot
of
the
identical
parts.
B
A
Right
yeah,
so
we
make
it
larger
Thanks.
You
know
the
larger
you
fuse
instead
of
five
eight
millimeter
rods
use
25,
millimeter
rods
for
a
machine,
that's
like
a
more
like
a
CNC
torch
table
or
a
router,
and
then
we're
also
planning
on
using
that
in
a
two
inch
and
three
inch
rod
version
for
super
heavy-duty
machining,
so
talking
about
making
engines.
So
this
is
where
I
talk
about
the
open
source
micro
factories
I
want
to
bring
all
that
kind
of
production
over
into
every
Fab
Lab
every
open
source
microfactory.
A
A
B
I
mean
this
has
a
very
low,
unique
power,
counts
and
I
think
the
it
is
easy
to
put
together
everywhere,
and
it
has
the
it
has.
The
extensibility
is
to
not
just
as
a
small
taste
of
winter,
but
the
whole
idea
can
be
extended,
so
this
mafia,
a
couple
different
level
of
course
coming
from
do
dinner
through
a
simple
XYZ,
all
the
ways
I
think
2d
to
how
to
get
this
to
be
a
large,
a
large
yeah,
a.
A
Yeah,
how
would
you,
how
would
you
do
is
be
a
thoughts
on
the
cost
structure,
won't
be
like
an
extended
course,
because
that'll
definitely
takes
take
some
development
right.
Is
that
something
we
should
do
right
now?
Let
me
know
so
that
we
can
leverage
that
for
just
training
a
lot
of
people,
I
think
so
that'll
be
interesting.
A
B
Could
you
have
a
conversation
with
the
the
fragmentation
in
a
couple
better
than
a
couple?
Fella
I
think
they'll
be
rod
up.
This
should
be
a
lot
of
interest
in
this
kind
of
structures.
Mm-Hmm,
that's
one
of
the
one
of
the
structure
was
was
supposed
to
be
delivered
by
the
election
for
no
but
never
get
around
to
it.
B
A
C
A
A
B
B
B
A
A
D
A
B
B
A
B
C
B
A
A
D
A
B
There's
always
the
vision,
I
think
that's
that's
always
divisions,
but
that's
just
nah,
that's
just
too
many
parties
or
wrong
so
and
never
get
to
that
that
wasn't.
There
was
such
a
big
mission
they
out
in
in
the
16,
but
oh
and
also
in
the
book
yeah
mission
is
always
there
is
the
the
the
whole
people
working
out
the
economic
models.
A
B
A
Now,
does
that
mean
that
before
I
go
out,
there
would
I
want
to
be
present
that
kid
is
already
available,
so
just
do
a
little
bit
of
work
and
make
it
available
before
like
because
I
like
to
publish
early
and
often
and
kind
of
like
involve
people
early
on,
but
should
we
actually
okay,
put
this
online
just
show
some
just
just
do
a
little
bit
more
work
on
it?
In
other
words,
just
just
in
terms
of
marketing,
it
just
mark
it
in
a
little
bit,
in
other
words,
no
gets.
A
B
Think
what's
the
website
and
it's
always
good
to
I-
think
what
for
open
source
our
project?
It's
always
good
to
have
to
always
get
into
the
place
where
you
see
the
project
and
that
as
she
other
than
teach
you
how
to
build
it,
that
is
she
a
place
to
click
on,
say.
Oh
I
want
to
buy
that
kid.
So
I
can
do
it
myself.
Okay,.
B
C
A
Yeah,
no
because
I
mean
if
they
could
get
involved
in
the
concept
to
actually
start
using
it,
but
more
than
that
to
actually
cause
the
next
step
on
that
for
our
heavy
machine
fabrication.
That's
building
the
open-source
CNC
torch
stable,
based
on
the
25
millimeter
version
of
this.
This
axis,
which
we've
done
a
prototype
last
year,
but
it's
not
a
product
release
actually
wanted
to
make
it
oxy-hydrogen
or
upgrade
operations.
So
you
don't
have
to
you.
Don't
have
any
feed
stocks
like
oxy-acetylene
or
even
electricity
like
I.
A
A
I
mean
one
thing
from
my
perspective
from
the
ecological
perspective
and
a
systems
perspective,
I
believe
that
oxy-hydrogen
is
a
way
to
go
instead
of
oxy-acetylene
or
plasma
cutters,
because
it's
a
low-cost
available
fuel
from
water,
and
it's
proven
it's
it's
well
proven,
and
actually
it's
one
of
the
things
like
it
exists
very
well
in
Aliexpress,
entirely
ba-bong,
so
I
know
they
do
have
a
lot
of
these
electrolyzers
or
on-demand
hydrogen
production.
That's
something
I'd
like
to
open
source
for
this.
C
A
A
What
I'm
saying
is
if
we
could
get
the
Fablab
around
doing
this,
but
it
kind
of
takes
them.
You
know,
like
kind
of
hard
convincing
people
of
these
kind
of
like
appropriate.
What
I
would
call
appropriate
technology
routes.
I'm
sure,
there's
gonna
be
a
bunch
of
resistance
to
that,
but
well
the
idea
that
they
could
get
involved
in
in
actually
developing
oxy-hydrogen
open-source
oxy-hydrogen
cutting.
You
know,
they'll
be
awesome.
B
I
think
the
the
Rena
is,
the
the
any
organization
will
have
resistance,
but
it's
also
through
the
network,
finding
the
20,
the
rare
few
who's
really
interesting,
and
we
like
to
contribute
yeah,
so
I
think
in
the
information
out
there
getting
the
message
out
there:
yeah.
Yes,
there.
It
is
tea
for
pork.
Again,
this
Brett,
oh
yeah,.
A
A
A
People
in
the
network
there
that
would
actually
appreciate
just
a
robust
super,
simple
design.
I
mean
there's
nothing
special
about
the
axis.
It's
very
simple,
but
I
think
that's
what
makes
it
very
powerful
and
flexible
I
think
there's
gonna
be
at
least
some
people
that
that
can
appreciate
this.
This
level
of
we
are
called
simplicity,
yeah.
